10 SUPER SHOT 125 DIESEL MELTER OPERATING INSTRUCTIONS INTRODUCTION The CRAFCO SUPER SHOT 125 MELTER was developed to melt CRAFCO Brand Sealant. However, it will work equally well with all road asphalt and federal specification crack or joint sealant. DO NOT operate machine without following these instructions: 1. Fill fuel tank with diesel fuel (use #1 in cold weather, #2 in warm weather). 2. Check engine crankcase oil level (refer to Engine Operator s Manual). 3. Check hydraulic fluid level, at 70 F. Add fluid if necessary. 4. Check heat transfer oil level, at 70 F., the oil should be at the full mark on the dipstick. DO NOT overfill or spillage may occur when oil is heated and expands. 5. All toggle switches should be turned OFF and both temperature control dials at minimum settings. 6. Remember that safe operation of this equipment is the operator s responsibility. CAUTION: Extreme care must be used when operating this equipment. Safety is the result of being careful and paying attention to details. Remember the diesel flame is about 2,200 F. Certain exposed parts of this machine, when operating reach 500 F.; the sealant as high as 400 F. and the hydraulic fluid may reach 200 F. Always wear protective clothing, hard-soled shoes, and eye protection. Be sure that all joints and fittings are tight and leak proof. Immediately replace any hose, which shows any signs of wear, fraying, or splitting. Tighten all bolts, nuts, and screws every 250 hours. 10

11 MACHINE START UP TO START BURNER 1. Fully open the damper vent. 2. Start engine per Engine Manual. 3. Turn burner toggle switch at control box ON. 4. Set hot oil temperature at 500 O F and material temperature at manufacturers recommended temperature. CAUTION: If burner does not ignite the first time, turn burner toggle switch to OFF. Turn burner toggle switch to ON again. Burner should ignite. If burner still does not ignite, determine cause of malfunction (see Trouble Shooting Guide, Page 29). NOTE: The solid material in the tank melts first around the walls and bottom of the material tank. Material temperature sensor is located by the wall; therefore, it is possible that the beginning of the melting process the indicated temperature reaches operating value, but the material closer to the center of the tank is still solid. This is normal and when the heated hose is ready for operation, most of the material in the tank will be melted and heated to application temperature. 5. Allow the heating oil to continue to heat. When sealant material reaches a liquidstate, engage the mixer by turning the toggle switch at the hydraulic control panel ON, open flow control approximately 3-4 turns. If the mixer does not move, allow the material to heat longer. Jamming of mixer causes hydraulic oil to overheat and machine damage could occur. When approximately half the material is melted turn the agitator speed up to approximately 6-8 turns (this will mix the material to even temperature throughout). 6. Turn ON the hose toggle switch when hot oil temperature reaches approximately 300 O F. See Operating Instructions. Adjust the temperature dial to 380 O F. The hose will come up to temperature in approximately 30 minutes. After the hose is hot, the light in the control box marked HEATED HOSE will turn off and the temperature may be reduced to approximately 360 O F. It is advisable to run the hose at the lowest temperature setting possible and still have material dispense. NOTE!! The hose must be up to temperature before dispensing can take place. IMPORTANT!! DO NOT twist or kink hose. Avoid sharp bends and continuous twisting. Maintain minimum, 10 inch bend radius. DO NOT exceed 400 O F. setting on hose controller!! DO NOT move or bend hose when cold. Damage may result. DO NOT leave hose ON for longer than 30 minutes without dispensing material. Coking will occur and permanently damage hose. DO NOT remove hose from boom during operation, kinking will occur. IT IS STRONGLY RECOMMENDED THAT THE HOSE BE STORED IN THE HOSE HANGER WHEN NOT IN USE OR WHEN IN TRANSIT. THIS WILL HELP PREVENT TWISTING OR KINKING. 7. The heated hose supplied with the machine is Teflon lined with steel over braid. It has a heating element, which runs down the hose to heat the material within the hose. The hose is covered with high temperature, durable rubber hose. The wand has an aluminum tube to protect both the wand and the operator. The pistol grip actuator is equipped with an electric switch which when depressed sends a signal to actuate the pump. At the end of the wand, a high temperature elastomeric output valve is attached. The valve is pressure actuated and opens automatically when fluid pressure is applied. The wand is equipped with a trigger lock to prevent accidental pump actuation when not pumping material. The trigger should be in the LOCKED position at all times except when intentionally pumping material. 11

12 DISPENSING THE MATERIAL NOTE: PROTECTIVE CLOTHING, GLOVES, HARD SOLED SHOES, AND FACE SHIELD OR SAFETY GLASSES SHOULD BE WORN WHEN OPERATING OR FILLING THIS EQUIPMENT. READ ENTIRE MANUAL BEFORE OPERATING. The wand is equipped with a disposable duckbill valve on the end, which shuts off the flow of material when the pump is turned off and prevents excessive dripping of material. This valve also directs the material into a stream for easy application into the crack. Other sealing tips are available. See your local distributor for options. Some difficulty may be encountered when starting up on cold days. Although the wand is designed to heat the material all the way down to the tip, on cold days it may be necessary to place the tip of the wand under the lid to facilitate material melting in the valve. Insert the wand tip for only a short time before proceeding. When the material and the hose have reached proper application temperature, you are ready to dispense material. Turn the pump speed control to the lowest setting by turning the speed control knob fully counter clockwise. With the wand tip inserted into the top of the melter, depress trigger on the wand and slowly increase pump speed by turning the speed control knob clockwise until the pump motor starts to turn. Material should start to flow from the tip of the duckbill valve. Adjust the pump speed for the desired rate of flow for the application and dispense material as required. The rate of flow may be varied while the pump is running by rotating the control knob. NEVER POINT THE WAND AT ANY PART OF THE BODY OR AT ANY OTHER PERSON. HOT MATERIALS CAN CAUSE SEVERE BURNS. WEAR PROTECTIVE EQUIPMENT WHEN FILLING OR OPERATING THE EQUIPMENT. READ MANUAL BEFORE OPERATING EQUIPMENT. ACTIVE PUMP PROTECTION The pump shall be completely encircled by a protective screen. The screen shall not allow anything larger than 1/2 (1.27 cm) in size to pass from the sealant tank into the pump suction port. The screen shall continuously rotate 360 around the pump whenever the sealant agitator is engaged. The active screen will protect the pump from foreign object damage and will self clean as it rotates around the sealant pump and suction port. 12

13 LOADING THE MACHINE When loading solid material into the sealant tank, the mixer will stop when the lid is lifted. To load, lift the lid, place the material on the lid and close lid. Following this procedure will prevent the hot material from splashing and causing serious burns to personnel. The solid material must be added at intervals, which will allow the mixer to rotate without jamming. If blocks of material are fed in too quickly, jamming will result and slow down the melting process. SHUTDOWN AND CLEAN-OUT PROCEDURE When shutting down the machine for the day, there are several schools of thought about how much material to leave in the machine. Crafco recommends leaving the melter about half full. This will give a fairly rapid heat up rate in the morning, but will allow enough material to start dispensing right away when the material becomes molten. 1. Turn the burner toggle switch OFF. 2. Reverse the pump for approximately 30 seconds. 3. Turn the hose controller toggle switch OFF. 5. Store the hose in the hose hanger per transport decal on machine. IMPORTANT!! DO NOT kink or twist hose, as permanent damage will result. 6. Turn the mixer toggle switch to OFF. 7. Shut the engine down by turning the key to the OFF position. STORING MACHINE The melter should be stored in an area where moisture cannot enter the machines heating system such as hot oil, controls, etc. Extended down time can cause moisture build up in heating oil tank. If there is any suspicion that moisture may have collected in heat transfer oil, warm heat transfer fluid to 300 F. for 2 to 3 hours to evaporate the moisture. 13

14 INSTRUCTIONS FOR ORDERING PARTS Parts may be ordered from your local CRAFCO distributor or directly from CRAFCO, Inc. if a distributor is not available in your area. When ordering parts, give the following information: 1. Part Number 2. Machine Model 3. Serial Number Write, telephone, or fax: CRAFCO, INCORPORATED 235 SOUTH HIBBERT DRIVE MESA, AZ Phone: Fax: Toll Free: ELECTRIC HOSE CARE AND CAUTIONS Twisting and kinking of the electric hose (used on LF, BAX, SS60, SS125, and SS250 Melter) is the number one cause of hose failure. When this happens, the electric heating wires are shorted out to the metal hose cover and the hose stops heating. This type of failure is not covered under the Crafco warranty. To help prevent twisting and kinking and the resulting hose damage, the operator should: a. Not move or use hose unless it has been turned on a least 30 minutes and set at a minimum temperature of 300 F. b. Make sure hose swivel between hose and wand moves freely. c. Limit the hose bending to a radius of 10 inches. d. Avoid bending the hose over sharp edges such as the edge of the frame or tank. e. Avoid twisting. f. Do not exceed 400 F. on the hose or material temperature. g. Follow all instructions of the melter as well as those in the instruction manual. 14

15 HOSE TRANSPORT INSTRUCTIONS 1. Remove hose from jib support and rotate jib support towards front of machine until it locks into position. 2. Wrap hose on hose hanger two complete wraps (Approximately 20 inch diameter). 3. Store wand in support hook. CAUTION: Hose damage will occur if: a. Hose is bent or moved when cold. b. Hose is twisted or bent at less than a 10 inch radius. c. Hose is moved prior to being turned on at least 35 minutes and set at 380 O F. d. Operator crosses over or under hose causing hose to twist or wires between hose and wand connection to twist or wrap up. e. Swivel is cold and not free to move allowing hose to twist. f. Hose to wand wiring is pulled, stressed, or used to support the wand. 15
